EDWIN I-I. COOPER, OF LOS ANGELES, CALIFORNIA, ASSIGNOR TO C. K. SYSTEMS COM- PANY, OF LOS ANGELES, CALIFORNIA, A CORPORATION OF CALIFORNIA.

LOOSE-LEAF CREDIT-BOOK.

To all whom it may concem:

Be it known that I, EDWIN H. COOPER, a

citizen of the United States, residing at Los Angeles, in the county of Los Angeles and State of California, have invented new and useful Improvements in Loose-Leaf Credit- Slip Books, of which the following is a specification.

This invention relates more particularly to that class of loose leaf account books designed to detachably hold in position on the several leaves a series of credit sales slips arranged in alphabetical order, and a main object of the invention is to provide a compact account holding book of a size that will permit of easy handling, and which may be placed in a small safe or other fire proof repository.

A further object is to provide a novel form of account holding book in which both sides of the leaves are utilized for holding account or credit slips, and one in which the leaves may be quickly detached therefrom and added thereto.

In the accomplishment of the above objects I preferably utilize a series of rectangular frames divided into a series of compartments or recesses, a metallic backing sheet being secured to the frames midway of their thicknesses to form compartments on both sides.

Each compartment is preferably provided with a spring bill holding clip, and each leaf has at one end thereof a hinge formed of a flexible material, to the outer edge of which is secured a rigid binding strip, preferably formed of wood and of the same thickness as the leaves. The whole series of leaves being detachably secured together by suitable covers.

In the drawings hereunto annexed and forming a part of this specification :-Figure 1 is a perspective view of an entire book having one of the covers broken away to disclose the construction of one of the leaves of the book. Fig. 2 is a longitudinal section of one of the leaves of'the book. Figthe original slip, while the duplicate is given to the purchaser. Heretofore these original Specification of Letters Patent.

Serial No. 514,352.

credit slips have been filed away, and at some convenient time the bookkeeper has transferred the information contained on the original bills to a set of account books. In order to file these credit slips away so as to be readily accessible at all times various filing devices have been designed, but in all instances of which I have a knowledge they have been cumbersome and of such a size that a small merchant who only possessed a small fireproof safe which could not accommodate the device, has been forced to post the accounts to his set of books at the end of each days business forfear of fire or theft.

By means of my compact credit slip holding account book, the slips may be allowed to accumulate a number of days before finally posting, or statements may be rendered di rectly from them, as the book is of such a configuration that it may be easily placed in a safe of ordinary dimensions at night.

Referring more particularly to the drawings, 5 designates a series of leaves or rectangular frames, having covers 6, 7 the whole being detachably secured together in a suitable manner, but preferably by means of studs 8 rigidly secured to one edge of cover 6, the upper end of the studs being screw threaded and engaged by screw threaded caps or nuts 9. As the construction of each of the leaves is exactly the same and for brevity of description I will describe only one construction.

Each leaf preferably consists of a rectangular frame formed of wooden strips 10, having at each of its four corners metallic angle protectors secured thereto in a suitable manner. The inner vertical faces of strips 10 are provided with horizontally extending rooves 11 which are formed in the vertical aces midway of their height. These grooves receive a metallic plate 12 preferably formed from aluminium, for the sake of lightness and durability and which forms the bottoms of a series of recesses or bill holding compartments 13 on either side of the leaf. These compartments 13 are formed on either side of backing plate 12 by a longitudinally extending and centrally disposed cleat or bar 14, these bars being intersected on either side by transversely disposed cross bars 15. Each bar 14 is provided adjacent each compartment with a notch 16 adapted to form a bearing seat in which a spring bill clip 17 is secured. This clip is fastened at its center, each of its ends pro ectin'g into a compartment as clearly illustrated in Figs.

1 and 3 of the'drawings, the bills or credit erably formed of leather and which forms a.

connecting hinge for each leaf. The transverse edge of this strip is secured to a rigid binding strip 19 midway of its thickness, the strips being held in detachable relation to each other by the studs 8 and caps 9 as was heretofore described.

It will be apparent from the above description that I have provided a compact device that will conveniently carry a large number of credit slips and which may be readily accommodated to the volume of busi ness being done.

It will be further observed that by forming the device into book form that the merchant may readily dispose of the same at night in a fire proof repository of usual capacity.

WVhat I claim is p 1. A leaf for a credit slip book, comprising a metallic backing having flanges around its edges, said flanges extending beyond each of the faces of the backing, a plurality of strips secured to each of the faces of said backing, said strips forming credit slip receiving pockets, a plurality of double spring clips mounted on one of said strips, said clips extending into the slip receivingpockets, a rigid binding strip secured to one edge of the backing, and a strip of flexible material for connecting the backing plate to the binding strip. 7

2.A leaf for a credit slip book, compriseeavee ing a rectangular frame, a backing plate mounted in said frame midway the thickness thereof, a plurality of division strips mounted on the faces of said plate, said di vision strips forming recesses, a plurality of double ended spring clips secured to one of said division strips on each face of the backing plate, each of the recesses having a clip projecting thereinto, a rigid bindingstrip, and flexible means for connecting said strip to said frame.

3. A leaf for a credit slip book, comprising a frame provided With a backing plate, said plate being mounted in said frame midway the thickness thereof, a plurality of division strips mounted on the faces of said plate, said division strips forming recesses, a plurality of spring clips secured to said division strips, each of the recesses having a clip projecting thereinto, a rigid binding strip, andflexible means for securing said strip to said frame.

f. A leaf for a credit slip book comprising a frame provided with a backing plate, said plate being mounted in said frame midway the thickness thereof, a plurality of division strips mounted on the faces of said plate, said division strips forming recesses, a plurality of spring clips secured to said division strips each of the recesses having a clip projecting thereinto, and a binding strip secured to said frame.

In witness that I claim the foregoin I have hereunto subscribed my name this 13th day of August, 1909.
